Minerals
These are naturally solid, inorganic substances that make up rocks
Minerals
How many types of rocks are there
3 types
What is the thinnest layer of the Earth and the layer in which we live
The crust
The lithosphere/crust is broken into these things that move
Tectonic plates
What are the 2 types of igneous rocks
Intrusive and extrusive
The color of a mineral in powdered form
Streak
The cycle that rocks go through to change from one kind to another
The rock cycle
The only liquid layer of the earth is the
Outer core
Tectonic plates float on top of this layer
Mantle/ asthenosphere
Molten rock material is called

Talc
This type of rock forms from lava or magma cooling and hardening
Igneous
This layer is the thickest layer and contains convection currents
Mantle
This type of plate boundary occurs when two plates slide past one another often causing earthquakes
